Broad license to user content
You are agreeing to give Meta a broad, sublicensable license to your content that may persist if third parties have used it.
“you grant us a non-exclusive, transferable, sub-licensable, royalty-free, and worldwide license to host, use, distribute, modify, run, copy, publicly perform or display, translate, and create derivative works of your content (consistent with your privacy and application settings). This means, for example, that if you share a photo on Facebook, you give us permission to store, copy, and share it with others... such as Meta Products or service providers that support those products and services. This license will end when your content is deleted from our systems.”
What that means: Meta can share your uploads with third-party partners and continue to hold rights to them even after you try to delete them if others have interacted with them.
The license is broad enough to allow sublicensing to partners and service providers. It also allows Meta to keep using the content if others have accessed it under this license before deletion, creating a gap where the license persists beyond user control.
